SEYMOUR HALLADAY, OF WESTFIELD, MASSACHUSETTS. PLAITING-MACHINE
FOR COVERING WHIPS.
Specification of Letters Patent No. 672, dated April 4, 1838.
To all whom it may concern:
Be it known that I, Seymour Halladay, of Westfield, in the county
of Hampden and State of Massachusetts, have invented a new and
useful Improvement on John Thorp's Patented Braiding-Machine,
called "Halladay's Improved Braiding-Machine," which is described
as follows, reference being had to the annexed drawings of the
same, making part of this specification.
The leading features of my machine resemble that invented by Mr.
Thorp, as will be seen by a reference to the annexed drawings and
as his machine is so well known these parts need not, therefore,
here be particularly described.
A, Figure 1, represents the main circular rim made similar in
both machines; B, under knees screwed to the rim A for supporting
the lower circle; C, upper knees also screwed to the rim A for
supporting the top circle E; D, lower circle screwed to the lower
knees, B; E, upper circle screwed to the upper knees C; F, the
gearing or cog wheels, with the carrier wheels H attached to them
and revolving on permanent axles G; G, axles fastened permanently
to the main rim.
The above parts are similar in both machines, excepting the
carrier wheels H. H, Figs. 1 and 3, carrier wheels, in which S
are the scores or cavities to receive the stud y of the racer J,
Fig. 2; I, Figs. 1 and 4, the oval plates or forms, made fast to
the axles for directing the racer; J, Fig. 2, the racer made to
travel in the grooves formed by the upper and lower circles and
the forms, by means of the revolving of the carrier wheels, in
which racer a is the shoe; b, front-plate; c, back plate, with
the single stud y, which enters the cavities of the carrier
wheel; d, bobbin wires; e, bobbin containing the substance to be
braided; f, spring for producing friction on the axle of the
bobbin to give a proper tension to the article to be braided.
Figs. 5 and 8 show the bobbin and spring detached; Figs. 6 and
10, Thorp's racer, and Fig. 9 a section of one of the circles.
The operation of my machine is similar to Mr. Thorp's.
The main feature of my improvement consists in the arrangement of
the oval-plates I, called forms; placed between the top and
bottom circles in order to guide the racer J, in its proper
course around the circle thus doing away with the use of the cant
wire in Thorp's machine and preventing the danger of the racer
dodging said cant wire and stopping the work. Also in the
construction of the carrier wheel H with four single cavities s
in the circumference thereof to receive the stud y of the racer
for propelling it around the circle instead of four pairs of
cavities M Fig. 7, for the two studs s s of Thorp's racer Fig. 10
Likewise in having but one stud y attached to the outside of the
racer instead of two placed between the plates as heretofore
used. Also in placing the shoe a, Fig. 2, (which travels around
in the grooves between the forms and circles,) betwixt the two
plates b, c, of the racer instead of the outside of the back
plate as in Thorp's racer as seen at N, Fig. 6, and causing it to
travel around between the edge of the carrier wheel and the
circles, as in his machine.
The invention claimed and desired to be secured by Letters Patent
1. The arrangement of the oval plates or forms I between the
circles as before described, in combination therewith.
2. The construction of the carrier wheel H with single cavities
in its circumference to receive the single stud of the improved
racer as before described.
3. The construction of the racer with one stud on the outside
instead of two studs between the plates and in placing the shoe
between the plates instead of on the outside.
